Stakeholder evaluation of market based approaches towards managing the adverse impacts of commercial fishing on the marine environment

Creator:: Swart, Brycen
Abstract:: Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic habitats remain serious problems in fisheries management. Management methods based on traditional command and control (CAC) approaches may meet with initial successes yet additional progress is often marginal, requiring managers to implement additional regulations to achieve...

Towards an approach based on resilience for assessing the potential impacts of sea level rise

Creator:: Scalise, Armando Hector
Abstract:: In this paper, I will analyze the nature of these problems and examine how recent approaches to SLRA have dealt with them. In addition, a framework for assessing the potential impacts of sea level rise is proposed, drawing upon the ecological concept of resilience (Holling 1978, 1984).

Effects of aerosols on the properties of deep convective clouds

Creator:: Brown, Daniel A.
Abstract:: Aerosols are tiny particles that serve as nuclei for cloud droplet and ice crystal formation. Increases in aerosol concentration lead to clouds with smaller but more numerous droplets. Some recent studies have found evidence that ice crystal size in deep convective clouds is also reduced by elevated aerosol concentrations. In...

Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...

Identifying habitat factors for canary rockfish (Sebastes pinniger) off Washington and Oregon using environmental data and trawl logbooks

Creator:: Vestfals, Cathleen D.
Abstract:: If fisheries managers are to effectively manage commercially exploited fish populations, a basic understanding of the factors that influence fish distribution and abundance is required. In 2005, efforts to identify Essential Fish Habitat (EFH) for the 82 groundfish species managed by the Pacific Fishery Management Council along the West Coast...

Report on internship conducted with Yap State Environmental Protection Agency (Federated States of Micronesia)

Creator:: Harrison, Thomas D.
Abstract:: This internship was supported and funded by the Yap State Environmental Protection Agency (EPA), the United States Department of the Interior, Office of Territorial and International Affairs, and the University of Oregon Micronesia and South Pacific Technical Assistance Program. What follows in this report is a description of the internship...

A complex signal to noise problem : determining the aerosol indirect effect from observations of ship tracks in AVHRR data

Creator:: Walsh, Christopher D.
Abstract:: Cloud reflectivity is a function of cloud liquid water content and droplet number concentration. Since cloud droplets form around pre-existing aerosol particles, cloud droplet number concentration depends on the availability of particles that can serve as cloud condensation nuclei. Given constant liquid water amount, increased availability of cloud condensation nuclei...

INDOEX aerosol optical depths and radiative forcing derived from AVHRR

Creator:: Tahnk, William Richard
Abstract:: The Indian Ocean Experiment (INDOEX) had as a primary objective determining the radiative forcing due to anthropogenic aerosols over climatologically significant space and time scales: the Indian Ocean during the winter monsoon, January-March. During the winter monsoon, polluted, low-level air from the Asian subcontinent blows over the Arabian Sea and...

Investigation of polycyclic aromatic hydrocarbons (PAHs) transport by suspended particulate matter (SPM) in the lower Columbia River and its estuary

Creator:: Gregg, Tiffany
Abstract:: This study aims to improve knowledge of how suspended particulate matter (SPM) affects hydrophobic contaminant transport in the lower Columbia River and its estuary, using polycyclic aromatic hydrocarbons (PAHs) as model compounds. It is hypothesized that PAHs are transported to the estuarine turbidity maximum (ETM), a prime feeding zone in...

Patterns of sediment accumulation in the Siletz River Estuary, Oregon

Creator:: Pakenham, Anna
Abstract:: Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...
